Q:Are galvanized steel tubes the same as degaussing steel tubes?
And the method of magnetic field created by means of electromagnets or permanent magnets. For analysis of residual magnetism, see table (1), select the demagnetizing method and system in combination with the conditions of the construction site (for example, given equipment, etc.). Table 1 magnetic remanence grade and welding conditions
Q:What does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
Q:What quota should be installed for heating seamless steel pipe?
Installation quota of seamless steel pipe project, if it is indoor engineering, sets of welded steel pipe, the price adjustment can
Q:Are steel tubes and round steel in weight or length when purchased?
A large amount of words is calculated by weight, less is usually calculated. According to the length between the length and quality of a material is usually a scaling. Steel belongs to the section, with the length of valuation, according to the classification of wall thickness and diameter; round steel belongs to building materials, mostly for the amount of weighing per ton of valuation, a small amount of more than according to the length multiplied by the conversion ratio of weight to that theory. But the latter is the valuation of tons of steel products between the uneven thickness, with uniform proportion will produce larger price difference, so the general price of different manufacturers are not the same, mostly depends on the quality, to a certain extent is to balance the diameter difference.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
Q:Seamless steel tube with the tube with what is the difference?
Of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good, pay attention to oh!!
Q:45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
Q:How many meters per ton of steel tube?
Metric tons are metric units and China adopts metric system, so what we Chinese usually say "ton" means "metric ton", which can be regarded as "metric ton"1 metric tons (tonne/metric ton) = 1000 kg1 tons = 1000 kg1 kg = 1000 grams
Covering an area of 150,000 m2, is with total assets of 500 million RMB,with annual production capacity of 500,000 tons. Currently, we has approximately 1000 employees, including many top-rankingtechnical experts and excellent management team.
